1 Claim.

The invention relates. to metallic building structures, and has for its object. to provide a building formed from a plurality of abutting panels having abutting channels at the sides of the panels and in which channels spaced insulating'sheets may be placed for insulating against heat and cold, and at the same time forming air chambers for preventing sweating of the panels.

A further object is to provide the webs of the channels with registering'spaced tongues adapted to be struck out to one side and bent over each other for rigidly holding the webs in engagement. Also to provide spaced rows of tongues adjacent the sides of the webs for drawing the webs in close engagement with each other throughout their width, particularly when the panels and channels are formed from relatively thin material,

A further object is to utilize the tongues on the webs for holding the insulating sheets in engagement with the inner sides of the channel flanges and with the inner sides of the panels.

A further object is to provide the flanges of the channels with tongues adapted to be struck outwardly for the reception of metal lathing, and then bent against the metal lathing for anchoring the lathing to the channels.

A further object is to form the ceiling from a channeled panel, similar to the wall panel and to secure sleepers to the flanges thereof by means of tongues in the flanges of the channels.

A further object is to utilize the air spaces between the insulating sheets as heating passages for heating the house,

A further object is to provide a metallic building formed from panels and provided with means whereby the building may be entirely assembled without the use of bolts, thereby reducing the cost of construction to a minimum.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it

' being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings:

Figure 1 is a perspective view of a portion of the side wall of the building and a portion of the enlarged scale through the sides of, the wall panels, showing the struck out tongues for anchoring the webs of the channels together.

Figure 4 is a transverse sectional view taken on line 4-4 of Figure 2.

Figure 5 is a detail sectional View showing the struckout tongues for anchoring the channel webs together.

Figure 6 is a detail perspective view of the lower end of one of the wall panels showing the opening therein for the heating system.

Figure 7 is a plan view of the foundation for the building, showing heating ducts adapted to register with panel chambers.

Referring to the drawings, the letter A designates the sidewall of the metallic building and B a floor or roof.

The side wall A isformedfrom a plurality of panels I, preferably thin gauge metal, and which panels are in side abutting engagement as shown. The sides of the panels I terminate in abutting channels having webs 2 and flanges 3. It will be noted that the panels of the floors and of the side walls form a smooth surface which may be 1 painted or otherwise decorated. To hold down the price of the building, the panels are formed from relatively thin sheet material, and to further hold down the cost of construction, an improved means is provided which will obviate the use of bolts and the securing means can be fabricated at the same time the sheets are bent to form. The channel webs 2, adjacent their inner and outer sides, are provided with vertically alined tongues 4 which register when the panels are put together, and to secure the Webs together it will only be necessary to bend the lugs or tongues to one side and over each other for securing the panels together and for drawing the webs into close engagement with each other. Two series of tongues are used on the webs adjacent their inner and outer sides to insure a flat engagement of the webs throughout their surfaces, particularly when relatively thin material is used. The bent-in tongues 4 also form means for holding insulating sheets 5 against the inner sides of the panels and against the inner sides of the flanges 3 for forming air chambers 6 in the wall structure.

The flanges 3 are provided with struck out tongues I, which are V-shaped and formed during the fabrication of the panels, and when struck outwardly with a tool extend through the metal lathing 8 and are bent downwardly as clearly shown in Figure 4 for anchoring the metal lathing 8 to the outside of the wall, so that said metal lathing may be coated with a layer of cement or other stucco 9. The adjacent tongues in all cases are preferably in reverse relation so the connected parts cannot work upwardly or downwardly in relation to each other, as would be the case if the tongues extended in the same direction.

The ceiling B has its smooth side downwardly disposed and its channeled side upwardly disposed, therefore it will be seen that a smooth ceiling is provided which may be coated in any suitable manner. Where a floor is to be placed over the ceiling sleepers ID are provided transversely across the channels and anchored thereto by means of tongues Ia as shown in Figure 4, which tongues are struck out in the same manner as in the wall structure. The panels I, adjacent their upper and lower ends, are provided with spaced alined series of tongues lb, adapted to register with tongues 10 carried by end walls ll of the horizontal panels la, therefore it will be seen that the ceiling panels are rigidly connected to the wall panels and the sleepers l may be utilized as a securing means for nails when a wooden floor is laid.

In Figure 1, it will be noted that short panels may be used to form the window opening l2 for the reception of a metal window frame, and the metal window frame may be secured in place by striking out tongues into the window frame in the same manner as when connecting the panels together.

The building is preferably supported on a foundation I3, as shown in Figure 7 and heated from a heating plant l4 having pipes l5 leading to various heat outlets l6 and H. The outlets I! are in communication with air spaces 6 of particular panels and the particular panels may be provided with register openings 18 for discharging the hot air into the rooms.

It is to be understood that the V-shaped tongues are to be formed when the panels are fabricated by making V-shaped incisions through the sheet metal; the tying together taking place when the parts are assembled, and at which time a bending tool is utilized for bending the registering tongues outwardly and over each other for securing the panels together and for drawing the webs 2 into close fitting engagement as shown in Figure 5.

From the above it will be seen that a metallic building structure is provided, which is simple in construction having a smooth inner surface and one wherein the use of bolts is obviated. It will also be seen that the amount of labor necessary to assemble the pre-fabricated panels is reduced to a minimum.

The invention having been set forth what is claimed as new and useful is:

A metallic wall comprising a plurality of sheet metal panels, the abutting sides of said panels being channeled shaped and having their outer flanges extending in opposite directions, a metal lathing engaging the flanges, struck-out lugs carried by the flanges and extending outwardly through the metal lathing, anchoring the lathing to the flanges and struckout lugs carried by the webs of the channels and overlying each other and anchoring said webs together, said struck out lugs of the webs being in vertical series and spaced from the inner sides of the panels and the inner sides of the channel flanges, and sheets of insulating material interposed between the inner sides of the panels and the adjacent tongues, and the inner sides of the flanges and the adjacent tongues.
